AI Technical Summary

Benefits of technology

The aminobisphosphonate compounds effectively reduce wear and friction, as demonstrated by reduced wear scar diameters and micropitting protection in various testing scenarios, enhancing the longevity and performance of gear systems.

Problems solved by technology

Industrial and automotive gears are often subjected to pressures and loads that cause wear on the gear surface and / or roller bearing elements.
In some cases, the stress imposed on a gear contributes to micropitting, a form of gear fatigue and a common gear failure mode.
However, not all antiwear additives provide effective surface protection.

[0126]Compounds of formula (I) can be prepared using the synthetic route described in Scheme 1. One or more dialkyl phosphites (II and II′) are reacted with one or more carbonyl compound (III and III′) and a primary amine (IV) which produces compound with formula (I) with the removal of water.

[0127]R1 and R10 are the same or different and are independently selected from C1-C20 linear alkyl, C2-C20 linear alkenyl, C3-C20 branched alkyl, and C3-C20 branched alkenyl; n is an integer from 1 to 7; each of R2, R3, R4, R5, R6, R7, R8, and R9 is the same or different and is each independently selected from H, C1-C10 linear alkyl, C2-C10 linear alkenyl, C3-C10 branched alkyl, and C3-C10 branched alkenyl; X is selected from the group consisting of H, hydroxy, and N(R11)(R12); and R11 and R12 are the same or different and are each independently selected from the group consisting of H, hydroxy, alkyl, alkenyl, and alkynyl.

Description

[0001]This application claims benefit of 62 / 396,465, filed Sep. 19, 2016.FIELD[0002]The present invention relates to novel aminobisphosphonate compounds useful as antiwear and / or friction modifier additive components, lubricant additive compositions and lubricant compositions each comprising such compounds, and methods for making and using the same.BACKGROUND OF THE INVENTION[0003]Industrial and automotive gears are often subjected to pressures and loads that cause wear on the gear surface and / or roller bearing elements. In some cases, the stress imposed on a gear contributes to micropitting, a form of gear fatigue and a common gear failure mode.[0004]Typically, gear systems require a specially formulated fluid to meet performance requirements. To reduce, or even prevent wear, antiwear additives are commonly added to lubricating compositions used to lubricate the gears. When under pressure, these additives form a protective layer on a gear surface. This protective layer separates th...
